Quick Hits: Using a custom property with hit highlighting

So you have a managed property with SummaryType set to Dynamic and you want to use that in the FAST Search Center but your results show up with <c0> tags instead of highlighted terms?  In the Core Results XSLT, replace the following:

<xsl:when test="hithighlightedsummary[. != '']">     <xsl:call-template name="HitHighlighting">         <xsl:with-param name="hh" select="hithighlightedsummary" />     </xsl:call-template> </xsl:when>

with a reference to your managed property ('redactedbody' in the example below):

 <xsl:when test="redactedbody[. != '']">
 <xsl:variable name="hh_fin">
 <xsl:call-template name="replace-string">
 <xsl:with-param name="text" select="redactedbody" />
 <xsl:with-param name="replace" select="'c0'" />
 <xsl:with-param name="with" select="'strong'" />
 </xsl:call-template>
 </xsl:variable>
 <xsl:value-of select="$hh_fin" disable-output-escaping="yes"/>
 </xsl:when>

and then add this implementation of replace-string:

<xsl:template name="replace-string">     <xsl:param name="text"/>     <xsl:param name="replace"/>     <xsl:param name="with"/>     <xsl:choose>     <xsl:when test="contains($text,$replace)">         <xsl:value-of select="substring-before($text,$replace)"/>         <xsl:value-of select="$with"/>         <xsl:call-template name="replace-string">             <xsl:with-param name="text" select="substring-after($text,$replace)"/>             <xsl:with-param name="replace" select="$replace"/>             <xsl:with-param name="with" select="$with"/>         </xsl:call-template>     </xsl:when>     <xsl:otherwise>         <xsl:value-of select="$text"/>     </xsl:otherwise>     </xsl:choose> </xsl:template>
